3.5.0rc1: Input shaping causes layer shifts!?

gloomyandy

@NeoDue Did you disable any pressure advance on the 2nd hot end?

NeoDue

@gloomyandy yes, my config.g has just one M572 command for both hotends and I commented that one out.

oliof

I did a bit of testing myself to see whether I can reproduce and maybe find some counter measures.

TL;DR: IS makes your machine angry, give it some oomph

I did my testing on a Ratrig V-Minion, a machine that is known for high speed capacity in its stock configuration. My changes: LDO2504 stepper motors on X and Y, and a Fly Super5 H723 board with Fly 2209 steppers.

I originally ran the motors at 1.4A each, and with those I got heavy layershifting with IS and none without running at 5k accel and 900mm/min jerk on a Squircle vase mode test print. I got repeated layer shifts at the same layer heights (0.3mm and 8ish mm), so it was pretty clearly the issue @NeoDue saw.

Then I remembered I checked with Jason from LDO the other week, and the rating on the LDO motors is in RMS, not Peak. So 1400 PEAK is 1000RMS (give or take), or just 40% of the motor performance. I gave the test print a go at 1700 PEAK and the higher layer shift went away completely and the lower layer shift was much less pronounced. At 2000 PEAK the lower shift was almost invisible.

Now, this is with a test print that is pretty benign since except for the concentric infill on the bottom layers it has no sharp corners. But if you have some current you can add to your motors do so. Note that you need to add active cooling at these higher currents.

Next test will be running with 5160s from a 3HC expansion board to see if running the motors at 2.5A PEAK resolves this issue fully or not.

NeoDue

@oliof thanks for that information!

I had tried running my steppers at max current but that did not help at least for the layer shifts @dc42 is working on at the moment. As soon as I get some firmware to test I surely will check if increasing the motor current again might help with the last layer shift.

What I also take from all this testing so far is that StealthChop seems to be more resistant against causing layer shifts with IS than SpreadCycle, at least in some cases.

oliof

@NeoDue I don't understand? I thought a) stealthchop switches to spreadcycle at speeds where IS is relevant, and b) has less torque than spreadcycle to boot.

NeoDue

@oliof First of all, as I have set it in my printer - unless I do the tests here for this issue - , I use Stealthchop (less noisy) but simply do not let the printer switch between modes. See here for the reason: https://forum.duet3d.com/topic/33756/rrf-3-5-0-rc1-shaking-rattling-in-stealthchop/2?_=1707412028143 . In a nutshell: Either use Spreadcycle or use Stealthchop, but do not let the controller switch.

That being said, I also had thought that StealthChop reduces torque. But as you can see from the tests above, I get much more layer shifts if I use Spreadcycle for the x and y steppers than I get using Stealthchop. This and @dc42's claim from his recent bench test that he sees only extruder faults that I assume can only cause layer shifts by causing blobs leads me to the conclusion that for some reason Stealthchop is less affected by such blobs. And this means for some reason Stealthchop must create more torque to overcome these... ¯\_(ツ)_/¯

Edit: this works fine at least for the speeds and accelerations my printer can handle - if it would work for yours however is another thing

dc42

@NeoDue @oliof here is an update, and comment on your recent posts:

I am still working out exactly what isa going wrong, but I believe there are at least two issue with extrusion when input shaping and pressure advance are combined. I haven't got to the bottom of this yet.
Some users have reported "bang" noises from stepper motors when IS is enabled. These could be coming from extruder motors because of the issues I have found with IS+PA.
Using IS should not demand more of the motors when it is configured - if anything it should demand less. So if increasing motor current reduces or eliminates layer shifts that only occur when IS is enabled, most likely it is covering up the underlying issue.
@NeoDue reported that the layer shifts largely went away when pressure advance was disabled. I would welcome more data points on whether disabling PA eliminates layer shifts that only occur when IS is configured.

oliof

@NeoDue I am currently testing at 5k acceleration and 300mm/sec target speed (not always reached on short segments, hence my increase in jerk to 900mm/sec). This is mostly because I know the machine in use can easily reach those speeds and print well enough with Klipper, so I have a comparable baseline for performance and quality.

oliof

@dc42 PA or not has no effect in my testing.

The harsh noises I heard clearly came from the motion system with no blobs in sight. In my testing, the layer shifts were in the Y direction -- most likely because my test machine is a bed slinger so that is where the most weight is.

oliof

@dc42 here is a full video of the print. Disregard the underextrusion, I am outrunning the melt capacity of my hotend.

NeoDue

@dc42 thanks a lot! That lets me hope - I prefer in general to run the steppers with a somewhat reduced current to avoid them getting too hot if the printer is running closed since they are located inside the compartment.

@oliof Hm, due to the fan noise I could not hear any noise from the motion system in your video (by the way, the printer seems to fast for the camera ). I wonder though if it is coincidence that your printer creates that layer shift in the very moment it is speeding up...

While max speed of my printer is actually a little higher (but I tuned it down for print moves since I found that part strength becomes somewhat reduced when printing that fast) I use only modest jerk and acceleration values since the J1 has rather heavy print heads with a direct drive extruder included, and I made them even heavier by adding more substantial cooling fans... I do fear a bit for the linear guide which is positioned much more off-centre than in your printer.

But: that one layer shift that actually started this topic (height 5.5...5.65mm in my test part) was indeed in Y direction as well, and that one seemed also unaffected by PA, at least it still occurred in my last test for @dc42. On my printer, it is "just" the gantry with the two print heads and their x steppers that is moving there and the Y motor is definitely quite a bit more powerful than the X steppers, therefore I am unsure if that is actually mass related.

But one step after another - first I will wait for @dc42 to find and solve that IS/PA issue, and then (if that layer shift and bang does not vanish from the solution) I will continue tests about that issue.

Thanks for that info. Please can you run a print until you have had some of the harsh noises, then send M122 (just once, because sending it resets the data I am interested in) and post the report here.

oliof

@dc42 just after the noises, or at the end of the print? If the latter, here goes:

This is after a print without IS and without Layershift

@oliof thanks. Can you try a print with IS enabled and PA disabled? I'm interested n the "min interval" field in the Move section, but currently the combination of IS and PA causes this value to be wrong for extruders. I'd like to see what this value is when that interaction isn't present.

oliof

@dc42 Will do that tomorrow.

@NeoDue @oliof please try the new firmware at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0. This fixes the interaction between extruder PA and IS.

If you get any layer shifts or hear any strange noises (e.g. bangs) from the motion motors, please run M122 and post the report here. Note, each time you run M122 it clears the accumulated debug data after reporting it, so only the first M122 report taken after a layer shift or strange noises contains useful data - although of course if you get another layer shift or strange noises after running M122 then you can run M122 again to report data relevant to those events.

oliof

@dc42 I will do so next weekend, unfortunately no play time beforehand.

NeoDue

@dc42 Great! I hope I can manage to test tomorrow or wednesday!
